I don't think your car will have a 3.2 V6 (CF3) ecu. The mods required to connect one up successfully to a CF2 156 would be considerable. To get my 156 JTS selespeed to connect up to snap on's fancy diagnostics equipment you have to enter it as an early 147 sele.
I don't claim to be that knowledgeable obviously, I'm only going by what Multiecuscan is telling me.
My car is a 156 2.5 V6 Veloce from 1998.
when I connect to the OBD socket Multi Ecuscan refuses to connect to the correct model and will only connect to the
156 3.2 V6 though it tells me it has the wrong ISO number.
It does not give an option for an ABS controller whilst connected to that model and will not connect to the ABS controllers for the 2.5 V6 either. leaving me with no way to tell if it's sensors or controller.
this is annoying because I have spent a lot of time fixing the dented wing, dented passenger door, non operating rear windows, scuffed drivers seat, nackered CD player, broken undertray, stone chipped front bumper, knocking drop link, broken headlamp washers and non operating status screen which is how the ABS came to light.
It's the last thing I need to fix and I can't get at it, I would be prepared to buy a whole set of ABS sensors if neccessary but can't be sure it would help in the present situation. To rub salt in is the fact that before I paid for the license for ecuscan when I was trying to see how useful it would be it did recognise an ABS controller!
